it takes a motorboat 1 1/3 hpurs to go 20 miles downstream and 2 2/9 hours to return. find the rate of the current and the rate of the boat in still water.
------------------
Find the speed up and downstream.
To find mi/hr, divide the miles by the hours.
----
The boat's speed is the average of the 2 speeds.
The current is the difference between boat's speed and speed wrt to the Earth.
